COMBINED SASH HOLDER AND WINDOW RELEASE.

Application filed April 6, 1925. SerialNo. 21,151.

To all whom it may concern: 7

Be it known that 1, JOHN L. ARMSTRONG, a citizen of the United States,residing at the city ofOhicago, county of Cook, and State ofIllinois,have invented certain new and useful Improvements in Combined SashHolders and Window Releases; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it 'appertains to make and use thesame.

This invention relates to sash holders generally but more particularlyto a window release device which is so combinedwith the sash holderlever that theoperation of the latter will effect the operation of suchdevice.

Railroad car windows frequently stick at the bottom against the sill ofthe window,

and this=renders it exceedingly difficult, if not quite impossible, toraise the window, and the object of the present invention is to providea device which, when the sash holder is operated to withdraw the catchfrom the side of the window casing, will be impinged against the windowsill, and thereby cause the window sash to be slightly elevated abovethe sill. WVhen the device has once been installedon a car window, itscontinual operation will prevent any serious sticking of the bottom ofthe window sash to the sill.

In the accompanying drawings which form a part of this applicationFigure 1 is an inside elevation showing an ordinary sash holder equippedwith the preferred form of the improvement, with the parts in normalposition- Figure 2 is a view similar to Figure 1 but showing the sashholder lever operated to release the sash, and the impinging bolt memberthrust downwardly Figure 3 is a view similar to Figure 1 but showing amodified form of the invention, and

Figure 4 is an elevationsimilar to Figure 3 but showing the positionofparts after the sash. holder lever has been operated to release thewindow.

Similar numerals of reference denote like parts in the several figuresof the drawing.

Referring particularly to Figures 1 and 2, 1 denotes the casing of thesash holder having formed therewith the usual dowels 2 to extend withinthe sash, 3 is an L-shaped sash holder lever pivoted as usual to a postholder such as is commonly used on railroad car windows. I

Slidably housed within the bottomof the casing is a thrust member 6which moves freely through a boss 7 projecting, from the bottom of. thecasing to contact the sill denoted by b. I a

This thrust member 6 is a pin. orshort bolt which is vertically disposedand is 1 capable of free movement through theboss 7 at the lower part ofthe casing 1, and this thrust member or pin is provided with a head 8whose upper surface is generally spherical as shown.

The lower end a of the L-shaped lever 3 is formed into a cam surface 9whose radius is sufficiently great to render the action of this camsurface gradual and therefore more forceful as will be hereinafter morefully explained.

When the window, to which the improvement is applied, is closed, theboss 7 will rest directly upon any suitable striker plate gnot shown),that is located within the win ow sill, and the pin 6 will therefore bedriven upwardly so that its head 8 will be in contact with thecamsurface 9, and at the same time the catch 10 carried by the outerface of the lower portion a of the lever will have been thrown by theforce of the spring 5 into the usual locking engagement with theordinary notches at th side of the widow casing.

When the lever 3 is elevated to release the catch 10 the cam will bedriven with great force against the head 8 of the plunger pin 6, andsince the radius of this cam surface is so great the operation of thecam will be all the more effective and forceful and the a usual forcethat is applied to pinch the lever able distance above the windowsill,the pin 6 will, ofcourse, drop by gravity, but when th sash is closedthis pin will be driven by the striker plate in the window sillupwardly, until its lower extremity is flush with the lower extremity ofthe boss 7 and its head in contact with the cam surface 9.

If it be desired that the pin 6 shall not drop by gravity in the mannerabove described, a coil spring 12 may be placed around the pin andconfined between the head and any suitable portion of the boss 7 so thatthe action of this spring will always tend to force the pin upwardlyinto contact with the cam surface, as clearly shown at Figures 3 and 4.

Attention is particularly 'called to the fact that there is noconnection whatsoever between the operating lever 3 and the pin 6, andthat when the window is closed the cam surface isin position to operateagainst the head of the pin whenever the lever 3 is elevated. p

In the present improvement the force of the plunger pin 6 is initiallyand at all times exerted directly against the striker plate in thewindow casing.

This invention may be utilized in connection with window sashes otherthan those used in railroad cars, such as the sashes of street railwaycars, busses, and even house windows, and therefore this invention isnot limited in its application.

What is claimed is:

'1. 'A combined sash holder and window release, comprising a casing, asash holder lever pivoted within said casing and terminating at itslower end in a cam member and a vertically disposed plunger pin slidablyguided within the bottom of said casing and adapted to be forced againstthe window sill by the action of said member.

2. A combined sash holder and window release, comprising a casing havinga boss extending from its lower face, an L-shaped sash holder leverpivoted within said cas-- ing and terminating at its lower end in a cammember, and a yertically disposed plunger pin slidably guided withinsaid boss and having a spherical head adapted to be engaged by saidmember to force said pin against the window sill.

' In testimony whereof I aflix my signature hereto.

JOHN L. ARMSTRONG.
